I love my Avalanche. My wife was not sure but she loves every thing about it now. I had a Chevy that would get 35 mpg on the highway but I traded mpg for how I feel after a long trip. To maximize fuel economy it shows when you are in V8 mode or V4 mode and it will show you how much mpg you are getting. By watching my "mode" I can get 21 mpg on the highway or 18 with the E85 fuel. Plus after driving from Iowa to Texas and back again I felt like I drove accross town. I wish I could afford one today for my wife.
The overall build is perfect and the interior is awesome.
Mud flaps should be standard to protect the finish.
